The age of the moon was indicated by the relative position of the moon 3c printed on the moon plate 3.

（考案が解決しようとする問題点）しかし、従来の時計においては月齢表示機構は
設計当初から、専用に設計されたものでないかぎ
り、あとからこの機構を時計に組込むにはむずか
しく、またうまく組込んだとしてもかなり厚くな
つてしまい、その製造のために多大な費用がかか
る事はまぬがれなかつた。また表示部分も小さ
く、デザイン面でもかなりの制約があつた。(Problem that the invention aims to solve) However, in conventional watches, the moon phase display mechanism was designed from the beginning, and unless it was specially designed, it was difficult to incorporate this mechanism into the watch later, and it was difficult to incorporate it properly. Even so, it would be quite thick, and it was inevitable that it would cost a lot of money to manufacture. In addition, the display area was small, and there were considerable restrictions in terms of design.

（問題点を解決する為の手段）そこでこの考案は、このような欠点を解決する
ため、カレンダ付の時計ベースにおいて、このカ
レンダ機構を利用して安価で薄型、しかもデザイ
ンバラエテイに富んだ月齢時計を得ることを目的
としている。(Means for Solving the Problems) Therefore, in order to solve these drawbacks, this invention was developed to create a moon phase clock that is inexpensive, thin, and has a wide variety of designs by using this calendar mechanism in a clock base with a calendar. The purpose is to obtain.

（作用）上記問題点を解決するため、カレンダー機構を
利用し、カレンダー歯車の歯数比を変更すること
により、日回し車を約22時間50分で１回転し、日
車を約29.5日で１回転させる構造として、安価で
容易に月齢表示時計に変更しうるようにしたもの
である。(Function) In order to solve the above problem, by using a calendar mechanism and changing the gear ratio of the calendar gear, the date wheel rotates once in about 22 hours and 50 minutes, and the date wheel rotates in about 29.5 days. It has a structure that rotates once, so it can be easily changed to a moon phase display clock at low cost.

（実施例）以下にこの発明の実施例を図面にもとづいて説
明する。第１図において、筒車１の回転を日回し
中間車６、日回し車７に伝え、日回し車７に係合
し、これと一緒に回転する日回し爪８を介してこ
の爪を日車９の内歯に係合させ、この日車９を間
欠送りさせる。又、日車９には前記内歯とは別に
係合溝９ａが設けられ、これと係合する爪３ｂを
持つ月板３が日車９と一緒に回転する。(Example) Examples of the present invention will be described below based on the drawings. In FIG. 1, the rotation of the hour wheel 1 is transmitted to the date drive intermediate wheel 6 and the date drive wheel 7, which engages with the date drive wheel 7 and rotates this pawl through the date dial pawl 8 that rotates together with it. It is engaged with the internal teeth of the wheel 9 to cause the date wheel 9 to move intermittently. Further, the date dial 9 is provided with an engagement groove 9a separate from the internal teeth, and the moon plate 3 having a claw 3b that engages with this groove rotates together with the date dial 9.

通常カレンダー機種においては、筒車１と日回
し車７の回転比が２：１となつており、筒車の回
転２回に対し、日回し車１回転、すなわち24時間
で日車を１歯送る。月齢表示機構おいては筒車
と日回しの回転比をおおよそ24：22.84としてい
る。このため日車は約29.5日で１回転する。 In normal calendar models, the rotation ratio between the hour wheel 1 and the date wheel 7 is 2:1, and the date wheel rotates once for every two rotations of the hour wheel, that is, the date wheel rotates one tooth in 24 hours. send. In the moon phase display mechanism, the rotation ratio between the hour wheel and the date dial is approximately 24:22.84. For this reason, the date wheel rotates once every 29.5 days.

22.84×31≒29.5 （ここで31は日車の歯数である）（効果）このように日回し中間車及び日回し車の歯数比
を変更し、筒車と日回し車の回転比を変えること
により簡単にカレンダー付の従来の時計を月齢表
示時計に変更しうる。22.84×31≒29.5 (Here 31 is the number of teeth of the date wheel) (Effect) In this way, by changing the ratio of the number of teeth of the intermediate date wheel and the date wheel, the rotation ratio of the hour wheel and the date wheel can be changed. By changing the clock, a conventional clock with a calendar can be easily changed to a moon phase display clock.

また第２図ａ，ｂ，ｃのごとく月令表示窓を三
日月型にすることにつて、一目で月齢表示時計で
あることを示すデザインとなる。なお、ａ，ｂの
窓形状が加工上の問題で、ｂのように二つの文字
板によつて窓５ａを形成することもできるし、さ
らに、またｃ，ｄのごとく渦流状となすこともで
きる。上記ａ〜ｅは、どれも同一の月板デザイン
で、窓形状の変更のみで対応できる。 Furthermore, by making the moon phase display window into a crescent shape as shown in Figures 2a, b, and c, the design shows that it is a moon phase display clock at a glance. Note that the shape of the windows a and b is a processing problem, so the window 5a can be formed by two dial plates as in b, or it can be formed in a spiral shape as in c and d. can. All of the above a to e have the same moon plate design, and can be handled by simply changing the window shape.
